<u>Answer:</u> The mass of the man on moon is 100 kg

<u>Explanation:</u>

Weight is the force exerted by the body on the surface. It s not same at every point in the universe. It is also defined as the mass multiplied by the acceleration of the object.

Mass is the actual amount of matter of an object. It remains the same at every point in the universe.

Mathematically,

W=m\times a

where,

W = weight of the man on Earth = 980 N

m = mass of the man = ?

a = acceleration due to gravity on Earth = 9.8m/s^2

Putting values in above equation, we get:

980kg.m/s^2=m\times 9.8m/s^2\\\\m=\frac{980}{9.8}=100kg

Mass of the man on Earth = Mass of the man on Moon = 100 kg

Hence, the mass of the man on moon is 100 kg

Ape species began to dwindle during the Miocene, leaving only a few remaining: a situation that exists up to the present. It is
fiasKO [112]

The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.

Explanation:

In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.

The sea-level got drop due to global cooling of that time.

This resulted in continental drift making land connection of Africa with Eurasia.

The primates started migrating through this route.

The African forest become dry causing selective pressures in primates.

The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.

The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.
